Y ApplicationfledDecember5,19.12. Seria1No.735,U-t2.

To all whom t may concern:

Bc it known that l, CHARLES E. Swim, a citizen of the United States, anda resident `of Danville, in the county of Vermilion and State of illinois, have invented a new and improved Binder, of which the following is a full, clear, and exact description.

My invention. relates to loose leaf binders, and is especially intended to produce a binder adapted to receive loose leaves consisting of cardboard or like mounts bearing `blue prints onopposite sides.

The invention will be more particularly explained in the specific description hereinafter to be given.

Reference is to be had to the accompanying drawings forming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of a binder embodying my invention, parts being broken away, the covers being shown opened; Fig. 2 is a transverse vertical section on approximately the line 2-2 of Fig. 1; Fig. 3 is a fragmentary view similar to Fig. 2, of the central portion of the binder, the arched impaling post being shown with the roclrable section thereof in the open position; and Fig. l1 is a transverse vertical section of the binder closed.

1n forming a binder in accordance with the illustrated example, 'covers 1G of any suitable material are flexibly united to a back 11, and rigidly secured to said back, longitudinally thereof, is a base 12, consisting of a strip of wood or metal. To the base strip 12, along one edge thereof, is a series of fixed sections 13 of arched impaling posts. Each impaling post comprises in addition to the rigid section 1S, which may be integral with the base strip 12, or secured thereto, a rockable impaling post section 14, said rockable sections being in Xed relation to a rock bar 15 held by staples 16 or equivalent means, in a longitudinal groove 122L along that edge of the base strip 12 opposite to the lower ends of the fixed impaling post section 13.

The roclrable section 111 moves in the plane of the fixed section 13, the two forming a complete arch which springs from the base strip 12 and ranges transversely thereof. Each rockable section 14E is formed with an integral foot 17 extending inward beyond the rock bar 15, over the base 12, against which footfa spring 18 bears, the spring being preferably a plate spring riveted as at 19 to the base strip 12. When in the closed position of the rocltable section 141, the spring 18 bears against the side surface of the foot 17 (see Figs. 2 and f1), while in the open position of the roclrable section the end surface of thc `foot 17 contacts with the spring 18, in l? ig. 3, so that the spring will act to hold the rockable impaling post section 14;, either in theopen or closed position, and a rocking of the bar 15 by grasping any one of the roclrable sect-ions, will move all the roclcable sections either against the fixed sections 13, or away from the latter. The integral feet 17 are received in transverse depressions l2b formed in the top surface of the base complementary to the longitudinal groove or concavity 12a. It will be observed that a fixed impaling post section 13 arches overthe base strip 12, from one side edge thereof to a point approximately above the opposite side edge, and terminates in a downward curve.

ln order to bind blue prints in my improved binder, leaves 20 are provided, of cardboard, stiff paper, or equivalent material, one leaf being shown in Figs. 1 to 3, and on each face of a leaf 20, a blue print 21 may be mounted, as shown in Fig. 1, preferably by pastors 22 at the corners of the blue print. Each leaf has holes 2B near the inner edge, as indicated in Fig. 2, that the leaves may swing on the impaling post sections from one side of the binding post t-o the other, and they may be removed from the impaling posts, or placed thereon when the rockable sections 14 are moved to the open position. I

My improved binder and mounts it will be observed has a capacity and form such that a large number of blue prints may be assembled in a single binder and accessible for conve-nient examination.

Having thus described my invention, I claim as new and desire to secure by VLetters Patent,-

In a binder,the combination with a back, covers {ieXibly connected with the back, and a rigid flat base stri secured to the inner face of the back; of iolding means on said base strip for loose leaves, said means comprising divided, arched, impaling posts, one section of each of which is immovably secured to the base strip at the back edge thereof, a roclrable rod to which the mating section of each post is connected, to be rocked toward or from the fixed section, the base strip having a longitudinally ranging ooneavity therein at the upper side thereof, at the front edge; and springs secured at one end of each to the base strip on the upper side of the latter, and ranging forwardly7 the roekable sections of the impaling posts having extensions at their' lower ends disposed beneath the springs, and the base strip having in the upper side thereof depressions for said extensions eomplenientary to the longitudinal coneavity. 1

In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.
